Application filed May 13,

To all whom it may concern:

Be it known that we, RALPH ERNEST GIB- soN, and HERBERT NiooLn, subjects of the King of Great Britain, both residing in Liverpool, in the county of Lancaster and Kingdom of England, have invented certain new and useful Improvements in Discharge Chutes, of which the following is a specification.

This invent-ion has for its object to provide means whereby red-hot coke pushed out of gas-re'torts, coke-ovens or similar apparatus, by means of discharging machines, may be delivered to a quenching-bench or other cooling apparatus, fixed outside the retort-house or in other convenient position, in an unbroken condition and as expeditiously as possible, or even into producers.

The object is achieved according to this invention by means of a tube, or tubes, preferably lined with lire-clay, through which the rcdhot coke passes from the retort to the cooling apparatus, (or to outside producers) and hinged so as to have a radial movement, curvedtubular bridge-pieces be ing provided for connecting the tube (or tubes) to the upper tiers of retorts. The tube and bridge-pieces are mounted on a travelling carriage to enable the tube to be moved along in front of the retorts and means are provided for adjusting the tube (or tubes) to any required position.

hen the coke is handled by these means the work is more economically, expeditiously, and better done than hitherto, the coke is of better quality, and, the retort-house is kept as free as possible from. heat, dust and fumes, with consequent greater comfort to the workmen.

The invention will be understood from the following description, reference being had to the accompanying drawings in which Figure 1 is a section through the discharging stage of a retort-house, showing our apparatus in side elevation adapted to work in conjunction with live tiers of horizontal retorts.

Figure 2 is a front elevation of the apparatus.

Referring to the drawings, 1 denotes the tube, which is preferably made in cross section to suit the shape of the retort from which the coke is discharged, and'of a convenient length to suit the width of the discharging stage. The tube is preferably lined with fire clay slabs bolted to a metal Specification of Letters Patent.

casing in such a manner as to allow for expansion and contraction.

The tube 1 is hinged or pivoted at its delivery end at 2, so as to be capable of being raised radially 'by hoisting means from the approximately horizontal position (illustrated by broken lines) in which it receives coke from the lowest tier of retorts to the inclined position (shown in full lines) for receiving coke from the uppermost tier of retorts.

The gap between the upper tiers of retorts 3 and the tube 1 due to the radial movement of the latter is bridged over by curved tubular bridge-pieces 4 of varying length and of a cross section similar to that of the tube. These. bridge-pieces are constructed and positioned in such a manner that the top of such bridgepieces will defleet the coke from its horizontal travel to the angle of the tube, and an unbroken path is always maintained between the retort and the point of delivery, the bridge pieces 4 being curved to such a radius that the coke passes down the tube in the same condition as it leaves the retort. The bridge-pieces 5 for the lower retorts may not be of tubular form, but flat orslightly curved, and set horizontally or at a slight inclination as required.

The tube 1, the bridge pieces 4 and 5 and the operating gear hereinafter vdescribed are mounted in a carriage 6, comprising a platform and a framework superstructure of any suitable construction. This carriage is adapted to travel by wheels 7 on rails 8 laid on the discharging stage 9 of the retort-house.

On the tube 1 is fixed a hoisting bridle 10, to which is connected a hoisting rope or chain 11 which passes over pulleys 12 at the top of the travelling carriage and thence downwards to a hoisting drum or the like 13.

The apparatus as described is operated by a reversible electric motor 1 1, supplied with current through a power-collecting arm 15 and is provided with spur-wheel reducing gear 16, 17 is the controller for the motor, 18 is the drivers platform. The machine could however, if desired, be operated by hand.

The hoisting drum 13 is driven from the.

motor by worm wheel reduction gear 19. 20 is a cluch for controlling the operation of the hoisting drum.

The travelling wheels 7 of the machine are driven through worm wheel reducing gear 21 and mitre-wheels 22, and the travelling gear is thrown into or out of operation by a clutch 23 which together with the clutch for hoisting drum is controlled by a handlever Qet mounted on the drivers platform.

v The mode of operation of the apparatus is as follows hen receiving the coke from the bottom tier of retorts 3, the tube 1 is held in an approximately horizontal position, (as shown in broken lines'in Fig. 1) forming what is practically an extension of the retort and connecting thereto as near as practicable. The coke is then pushed by the discharging machine direct into the tube in the natural form, a portion being delivered direct to the cooling apparatus in cases where the tube is shorter than the retort and the tube is then inclined on its hinge 2 to an angle suflicient to deliver the remainder of the coke by gravity to the quenchingtable 25.

hen receiving coke from retorts at a higher level than the point of delivery, the receiving end of the tube is inclined to a suitable angle by operating the hoisting gear and the gap between the retort and the tube due to the radial movement of the tube is bridged over by one or the curved bridgevpieces 4 in such a manner that an unbroken path is always maintained between the r tort and the point of delivery, and the coke is deflected from its horizontal path and passes down the tube in the same condition as it leaves the retort.

The space between the delivery end of the tube and the inclined quenching-table 25 is bridged by the hinged apron-plate 26, 27 is a vertically sliding door for closing the opening in the wall of the retort-house if desired and is fitted with balanceweights 28.

In thus describing the invention, we do not limit ourselves to the particular details described, as modifications in various parts of the apparatus, such as in. the operating mechanism and in the construction of the hinged tube, bridge-pieces and travelling carriages may be made without departing from the scope of the invention.

e declare that what we claim is 2-1 1. A discharge chute mechanism for furnaces of the type having carbonizing chambers arranged in superposed tiers, comprising in combination, a carriage arranged to travel along the furnace front; a plurality of superposed tubular guides mounted on said carriage in position to register with successive tiers of said chambers; and a tube movably mounted on said carriage so as to be capable of registering selectively with said tubular guides.

2. A. discharge chute mechanism for furnaces of the type having carbouizing chambers arranged in superposed tiers, comprising in combination, a carriage arranged to travel along the furnace front; a plurality of superposed curved tubular guides so mounted on said carriage that one end of each guide will register with chambers of a corresponding tier, the opposite ends or the guides terminating substantially on an arc of a circle and a tube hinged to said carriage substantially at the center of said circle and capable of swinging into register selectively with said tubular guides.

33. A discharge chute mechanism for fun naces of the type having carbonizing chambers arranged in superposed tiers, comprising in combination, a carriage arranged to travel along the furnace front; a plurality of superposed tubular guides mounted on said carriage in position to register with successive tiers of said chambers except the lowest; and a tube movably mounted on said carriage so as to be capable of registering selectively with any 0t said tubular guides and with retorts of the lowest tier.

4. A discharge chute mechanism for flu naces of the type having carbonizing chambers arranged in superposed tiers, comprising in combination, a traveling carriage; a plurality of curved bridging guide tubes varying in length and mounted in said can riage so as to register with upper tiers of retorts; a discharge tube conforming in cross-section with said retorts and with said bridging guide tubes, said discharge tube being pivoted at its delivery end to said carriage and being capable of swinging into register with any of said bridging tubes; and hoisting means for 'aising and lowering the receiving end of said tube.

5. A discharge chute mechanism for furnaces ot the type having carbonizing chainbers arranged in superposed tiers, comprising in combination, a. travelling carriage; curved bridging tubes mounted in said carriage; a discharge tube hinged at its delivery end to said carriage audrapable of swinging into register with said bridging tubes selectively; hoisting means for raising and lowering said discharge tube; an electric motor on said carriage; and driving connections whereby said motor may propel said carriage or operate said hoisting means selectively.

In witness whereof, we have hereunto signed our names this 1st day of May 1922, in the presence of two subscribing witnesses;
